Corrie's parents have not received justice, but their quest reveals the lie of the IDF's claim to be the world's 'most moral army'

Reporters covering Israel are routinely confronted with the question: why not call Hamas a terrorist organisation? It's a fair point. How else to describe blowing up families on buses but terrorism?

But the difficulty lies in what then to call the Israeli army when it, too, at particular times and places, has used indiscriminate killing and terror as a means of breaking Palestinian civilians. One of those places was Rafah, in the southern tip of the Gaza strip, where Rachel Corrie was crushed by a military bulldozer nine years ago as she tried to stop the Israeli army going about its routine destruction of Palestinian homes.

Gaza Strip today is facing a very harsh siege which is expected to have severely negative humanitarian impact.

The distribution of drinking water and the collection and treatment of wastewater completely rely on electricity and fuel in Gaza Strip.

For several months now Israel has imposed a cruel siege on the Strip preventing people and goods from free movement. This has immobilized the importing of spare parts, pumps, pipes and other necessary accessories for the water and sanitation providing facilities.

According to different sources the water and sanitation services are expected to be completely paralyzed within a matter of hours due to the lack of fuel reserves.

About 133 water wells are being used for domestic purposes in addition to 33 sewage pump stations and three treatment plants; 10 of these groundwater wells function using fuel while the rest rely on electricity. Diesel powered generators are normally used as backup for the whole system but only for a limited time. The Coastal Municipalities Water Utility needs at least 100,000 liters of diesel per month to operate the water system. An additional 100,000 liters of diesel per month are needed for the sewage system to prevent wastewater from flooding the streets and residential areas.

Reducing electricity and fuel supplies are potential causes to trigger an environmental crisis especially in the wastewater pump stations and treatment plants. If wastewater is not treated it will have to be pumped directly to the sea. This will for sure have a direct and negative impact on the groundwater aquifer and marine life.During winter time sewage pumps need to operate about 24 hours per day due to rainfall. Therefore, interruptions in fuel and electricity supply would be particularly significant.

The sewage treatment plant in Beit Lahiya is also vulnerable to interruptions in electricity supplies. The treatment lagoons must be pumped regularly, or else the 10,000 people living in the area are in danger. Six months ago, one of the lagoons over flooded and caused the death of five persons. Proper maintenance could have prevented the disaster.

The water supply in Gaza City, with a total of 600,000 residents, in addition to a major part of the central portion of the Strip is expected to be completely cut-off as a result of ceasing the pumping from the municipal groundwater wells. The City also faces the threat of overflowing wastewater since the pumps (especially Al Samer and Aqoola stations) are expected to stop operating within the next 24 hours.

If the current situation should persist the solid wastes generated in the Strip will accumulate in piles on the streets endangering the health of the locals.

The WaSH Monitoring Program calls on the International Community to push Israel to immediately cease all military operations, reopen the borders to allow the movement of people and goods and provide fuel supply and humanitarian aid to the residents of Gaza.
